I have a desktop version of Twin Rail Mobius that takes 10mm balls (not for sale directly from me but via a 3rd party) - ok, it cuts it very fine on the bounding box limits. I just checked, the outer diameter is max 125.5mm with max height 26.7mm in the orientation as uploaded - somehow it works.

Not much at all, Ive had a couple of rings out now by barely 1 or 2 mm-hence the frustration.
they were not overly flamboyant, ridiculous sized rings either.
It sucks because I don't want to alter the designs, i could sell smaller sizes, but it would seem a shame not to have all sizes available.
I also don't want to leave SW to do this as I've always been happy with the Sterling service, but I've seen other that offer bounding boxes with more practical sizes ie: wouldn't a 60mm cube be more accommodating for most Sterling objects (eg jewellery) than a box 110x110x30 ?

Dear Shapeways,
you have not replied to questions on the bounding size of sterling sliver posted in 2010 and 2011, it is now 2013, there are 3D printers which can print waxes to larger dimensions than your current of 30mm max.
If the sales volume is low on silver and not economical to purchase a new machine, how about also offering the sale of just the waxes without the casting, this will allow the end user more flexibility in what material they can cast in or use electroforming.

I'm sure the other materials wont have the detail, anyway the new developments sound hopeful .
It would be great to find somewhere that did wax...I would even pay a premium postage/make the designs sturdy enough to ensure they arrived in one piece. That said, I fully understand SWs decision not to.
The local casters here are good if you have your own wax, but the charges for them to print just one wax alone is astronomically out of my price range :/

I would definitely pay more too ... now I have $400 worth of FUD models that are pretty much useless for casting. One sample the casters did came out horrible. The FUD material expands before melting, and cracks the plaster. I wish there was more documentation from shapeways on this material's properties. The small / private jewelry industry would probably double SW's revenue if they used a material that could be burnt out properly...

Hey - I found that article too and discussed it with my caster - he said there is no way he would run his oven at that temperature , said it might burn out his element, but that might not be the case for casters with larger , hotter ovens ... Anyways , that's all I heard back. Cheers
